Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glass furnace auxiliary equipment, and in particular to a charging machine and a charging method for a rectangular glass all-electric melting furnace. Background Art
[0002] As an important industrial and civilian material, glass is widely used in many fields, including construction, electronics, optics, and daily necessities. The melting process is a key step in the glass production process, directly determining the quality and performance of the glass. With their unique advantages, all-electric melting furnaces occupy a key position in the glass melting field.
[0003] Its all-electric melting furnace uses electricity as a heat source. Compared with traditional fuel melting furnaces, it has significant advantages such as precise temperature control, low environmental pollution, and high energy utilization efficiency.
[0004] However, when a fully electric melting furnace melts glass, due to the different types of glass it melts, the types of raw materials used, the ratio of raw materials to broken glass, and the different arrangements of electrodes, etc., the melting speed varies across the entire furnace surface, deteriorating the melting quality. If a local area in the furnace melts too quickly, the glass liquid level in that area will rise, making the furnace prone to roof collapse and heat imbalance, which will not only damage the furnace equipment but also cause production interruptions. If a local area melts too slowly, the raw materials will accumulate, forming a "dead material zone", affecting the fluidity and uniformity of the glass liquid, resulting in defects such as bubbles and streaks in the glass products, and reducing product quality.
[0005] At present, most traditional feeding equipment uses a simple mechanical feeding method with fixed feeding amount and feeding speed, and cannot be adjusted in real time according to the changes in the melting speed in the all-electric melting furnace. When the melting speed in different areas of the furnace differs, the traditional feeding equipment cannot change the feeding strategy in time, resulting in unreasonable distribution of the batch material on the liquid surface of the furnace, further aggravating the problems of uneven melting speed and heat imbalance. Summary of the Invention
[0006] In order to solve the technical problem that the existing charging equipment cannot make real-time adjustments according to the changes in the melting speed in the all-electric melting furnace, the present invention provides a charging machine and a charging method for a rectangular glass all-electric melting furnace.

[0017] Through the above technical solution, the precise transmission and tensioning adjustment of the feeding belt can be achieved through the combination of the belt drive roller and the belt tensioning mechanism.

Preferably, in step B, if a kiln with a daily melting capacity of less than 30 tons is used, the single-feeder scheme D trajectory is preferred; if a kiln with a daily melting capacity of 30 to 50 tons is used, the single-feeder scheme A and B trajectory are preferred; if a kiln with a daily melting capacity of more than 50 tons is used, the single-feeder scheme C trajectory is preferred; if a kiln with a daily melting capacity of more than 100 tons is used, the double-feeder scheme E trajectory is preferred.
[0019] In summary, the present invention has the following beneficial effects: 1. The present invention enables the guide rail support frame to slide on the guide rail of the feeder and the feeding arm to slide on the guide rail support frame, so that the feeding position and feeding method can be flexibly adjusted, so that the distribution of the batch material on the liquid surface of the kiln is more reasonable, and combined with the real-time monitoring of the data monitoring module, it can make real-time adjustments according to the changes in the melting speed in the all-electric melting furnace, overcoming the defects of traditional feeding equipment that the feeding amount and feeding speed are fixed and cannot be adjusted in real time, and effectively solving the problem of unreasonable distribution of batch material caused by the difference in melting speed in different areas of the kiln; avoiding the situation where local areas in the kiln melt too fast or too slow; reducing the accumulation of raw materials and the formation of "dead material zones" caused by slow melting in local areas.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the specification disclosed below. The present invention is further described in detail below with reference to the accompanying drawings.
[0027] Example 1: A charging machine for a rectangular glass all-electric melting furnace, such as Figures 1-12 As shown, it includes a kiln charging area 106 and a charging machine 1 movably installed on one side of the kiln charging area 106. The charging machine 1 includes a guide rail support frame 2, a charging arm 3 and a feeding system 6. The guide rail support frame 2 is slidably installed on the charging machine guide rail 9 through the charging machine transverse transmission device 8. The charging arm 3 is slidably installed on the guide rail support frame 2 through the charging arm displacement device 7. A charging fixed frame 103 is installed on the guide rail support frame 2. The feeding system 6 is mounted above the charging arm 3 through the charging fixed frame 103. A feeding belt 4 is movably sleeved on the charging arm 3. The discharging end of the feeding arm 3 is facing the kiln feeding area 106, and the material is telescopically spread in the kiln feeding area 106. The feeder transverse transmission device 8 adopts a servo plus turbine deceleration transmission method, and the track is positioned by rack and pinion to ensure precise braking positioning and avoid the influence of inertia. The feeding arm 3 is a V-shaped roller welding support with an installation space inside. A plurality of belt guide rollers are provided on the feeding arm 3. The feeding belt 4 abuts against the belt guide roller and is driven by the belt adjustment system 5 to stably convey the batch material on the feeding arm 3.
[0028] The feeding belt 4 is preferably in the form of a vertical folding rib, and a plurality of guide rollers 105 are provided on the feeding arm 3. The plurality of guide rollers 105 are fitted with the feeding belt 4. The vertical folding ribs can effectively prevent the batch material from spilling from both sides of the belt during transportation, thereby increasing the loading capacity of the belt. The guide rollers 105 fit the feeding belt 4, and guide the running trajectory of the belt more accurately to prevent the belt from deviating, ensuring that the belt always runs on the correct path, and improving the accuracy and stability of transportation. Multiple guide rollers 105 are provided to disperse the pressure on the belt during operation, reduce the wear of individual components, extend the service life of the guide rollers 105 and the belt, and optimize the long-distance running state of the belt, so that the belt is more stable during transportation, reduce vibration and noise, and improve the performance and reliability of the entire feeding system.
[0029] The feeding arm 3 is provided with a belt adjustment system 5, a water-cooled heat exchanger 104 and a data monitoring module. The data monitoring module is located at the discharge end of the feeding arm 3. The belt adjustment system 5 and the water-cooled heat exchanger 104 are both installed at the other end of the feeding arm 3. The data monitoring module is a detector 101. (temperature sensor and material level sensor) and gravity sensor, the detector 101 and gravity sensor are located at the discharging end of the feeding arm 3, and the gravity sensor is located on the feeding arm 3 below the feeding belt 4 and abuts the feeding belt 4, while the detector 101 is protrudingly set on the side of the discharging end of the feeding arm 3. The collected signal data is fed back to the control system for intelligent conversion and then output to the transmission control for supplementary feeding at fixed points or local areas. All electronic components on the feeding arm 3 are water-cooled, and the water cooler is a closed and independent cycle. The entire cooling system is placed on the feeding arm 3, and the water-cooled heat exchanger 104 at the tail of the feeding arm 3 is used for cooling. The feeder 1 performs system intelligent conversion and physically enforced soft and hard dual safety limits through an external control cabinet.
[0030] The guide rails are laid according to the daily melting capacity (tonnage) of the kiln, which is rectangular in shape.
[0031] like Figure 9 and Figure 10 As shown, when the daily melting capacity of the kiln is less than 30 tons, its area is small, and the guide rails are laid on its long side so that the feeder 1 moves along the long side, reducing the number of track changes. The feeder 1 moves horizontally, and the feeding arm 3 extends into the kiln feeding area 106 to vertically lay the material. The width of a small kiln is narrow. If the guide rails are laid on the wide side, the feeder 1 needs to change the rails frequently, which increases the complexity of the operation and the time cost. like Figure 6 、 Figure 7 、 Figure 8 and Figure 11 As shown, when the daily melting capacity of the kiln is greater than 30 tons, the width is sufficient and the guide rails are laid on its wide side. At this time, the charging machine 1 moves vertically and the charging arm 3 lays the material horizontally.
[0032] like Figure 1 and Figure 5 As shown, the belt adjustment system 5 includes a belt drive roller 51 and a belt tensioning mechanism 52. The belt drive roller 51 is rotatably installed on the driving end of the first servo motor 53. The belt drive roller 51 is connected to the feeding belt 4. The first servo motor 53 is movably installed on the feeding arm 3 through the belt tensioning mechanism 52. The feeding belt 4 is driven by the belt drive roller 51 to rotate and feed on the feeding arm 3.
[0033] The servo motor has high precision and high response speed, and can quickly adjust the speed and direction according to the instructions of the control system, thereby ensuring the stable transportation of the feeding belt 4.
[0034] The belt tensioning mechanism 52 includes a fixed plate 521, a movable plate 522, and a tensioning bolt 523. The first servo motor 53 is screwed to the movable plate 522, which is movably mounted on the fixed plate 521 via the tensioning bolt 523. The fixed plate 521 is screwed to the feeding arm 3. During the feeding process, the tension of the feeding belt 4 may vary due to changes in factors such as the type, humidity, and particle size of the raw materials. By adjusting the tensioning bolt 523, the position of the movable plate 522 can be flexibly adjusted, thereby changing the position of the first servo motor 53 and the belt drive roller 51, thereby adjusting the tension of the feeding belt 4, ensuring the stability and continuity of the feeding process. Appropriate belt tension can reduce belt wear and slippage, thereby extending the belt's service life. Adjusting the tension can also prevent equipment failures and safety hazards caused by excessively tight or loose belts.
[0035] When the first servo motor 53 or the belt drive roller 51 fails, the related components can be easily disassembled and replaced, reducing maintenance time and cost.
[0036] The feeding arm displacement device 7 includes a feeding arm guide wheel 71 and a feeding arm telescopic transmission wheel 72. The feeding arm guide wheel 71 is movably installed on the guide rail support frame 2 in a centrally symmetrical manner. The feeding arm telescopic transmission wheel 72 is rotatably installed on the guide rail support frame 2 by a second servo motor. The feeding arm telescopic transmission wheel 72 is located between the feeding arm guide wheels 71, and the output end of the second servo motor is connected to the feeding arm telescopic transmission wheel 72 through a bevel gear.
[0037] A side surface of the feeding arm 3 close to the guide rail support frame 2 is provided with a slide rail and a rack, that is, the bottom surface, which is located below the rotating side of the feeding belt 4, and the two do not interfere with each other.
[0038] The rack is meshed with the feeding arm telescopic transmission wheel 72. The meshing transmission method can realize precise power transmission, so that the feeding arm 3 can perform telescopic movement according to the predetermined speed and stroke. The rack transmission has a high load capacity, ensuring that the feeding arm 3 can still operate stably under heavy load conditions.
[0039] The number of slide rails is preferably two, and the slide rails are adapted to the feeding arm guide wheels 71. The two feeding arm guide wheels 71 are symmetrically arranged on the left and right sides. The cooperation between the guide wheels and the slide rails converts sliding friction into rolling friction, reducing the wear between the feeding arm 3 and the guide rail support frame 2, providing stable guidance for the telescopic movement of the feeding arm 3, ensuring that the feeding arm 3 maintains linear motion during the movement, avoiding offset or shaking, and dispersing the stress of the feeding arm 3 to avoid the feeding arm 3 from tilting.
[0040] The feeding system 6 includes a mixing silo 61, a screw conveyor 62, a guide trough 63 and a belt speed measurement system 65. The mixing silo 61 is connected to the guide trough 63 through the screw conveyor 62. The screw conveyor 62 and the guide trough 63 are mounted above the feeding arm 3 through a feeding fixed frame 103. The belt speed measurement system 65 is installed in the feeding arm and adopts a servo-controlled spiral form, that is, the third servo motor controls the unloading of the screw conveyor 62. The inner diameter of the spiral is 150mm~300mm. For the feeding arm 3 with a width of 350mm~800mm, a double-spiral configuration is preferably used. For a belt width greater than 800mm, a triple-spiral configuration is optional. A closed dust collector 64 is installed at the discharge port of the screw conveyor 62. The screw conveyor 62 and the guide trough 63 are connected through the closed dust collector 64 to reduce the impact of material splashing on the working environment.
[0041] The belt speed measurement system 65 is located on the feeding arm 3 near the side of the belt adjustment system 5. A speed sensor is preferably used. The belt speed measurement system 65 is communicatively connected to the screw conveyor 62 so that the spiral unloading speed is intelligently fitted with the belt speed of the feeding arm 3. The batch material output from the screw conveyor 62 is evenly arranged on the belt, thereby improving the uniformity of the material laying of the feeding arm 3 in the kiln feeding area 106.
[0042] Example 2: A method for feeding a rectangular glass all-electric melting furnace with a feeder, such as Figures 1-12 As shown, the following steps are included: Step A: Before starting, check whether all components of the feeder 1 are operating normally; Step B: According to the melting amount of the kiln, the feeding track 107 is set, and the feeding arm 3 realizes uniform distribution of the material on the entire liquid surface through the reciprocating motion of the overall track change and the extension and contraction of the feeding arm 3 in combination with various combinations; like Figure 13 As described above, no matter what kind of feeding trajectory 107, the starting feeding distance of the feeding arm 3 close to the kiln feeding area 106 when feeding is S, and during the feeding process, the number of moving tracks of the feeder transverse transmission device 8 is S2, where S is S1+X*S2, and the value range of X is 0~2, which can accurately control the starting position of feeding and the moving distance during the feeding process to ensure uniform feeding.
[0043] like Figure 9 and Figure 10 As shown in the figure, if a kiln with a daily melting capacity of less than 30 tons is used, the single feeder 1 and the D scheme trajectory are preferred to achieve the D1+D2 motion trajectory combination. This is designed based on the production characteristics of small-scale kilns, while meeting production needs and reducing equipment costs and operating energy consumption. like Figure 6 and Figure 7 As shown, if a kiln with a daily melting capacity of 30 to 50 tons is used, the preferred single feeder 1, A and B scheme trajectories, can achieve the cyclic motion combinations of A+A, A+B, and B+B; like Figure 8 As shown, if a kiln with a daily melting capacity of more than 50 tons is used, the single feeder 1 and the C scheme trajectory are preferably selected to achieve the C1+C2 motion trajectory combination; like Figure 11 As shown, if a kiln with a daily melting capacity greater than 100 tons is used, a double feeder 1 and the E scheme trajectory are preferred. The wide side of the kiln is wide enough, and a single feeder 1 is not sufficient to meet the requirements of rapid cyclic material laying. Both feeders 1 can adopt the operation trajectory scheme of a single feeder 1.
[0044] The feeding track 107 is set according to the melting capacity of the kiln. The targeted design ensures that the feeding process matches the actual production needs of the kiln. By properly setting the feeding track 107, problems such as local over-high or over-low temperatures and uneven glass liquid composition caused by uneven feeding can be avoided, thereby improving the quality of glass products.
[0045] For large-scale kilns, by increasing the number of feeders 1 and optimizing the feeding trajectory 107, the production demand for high melting volume can be met, ensuring the stability and efficiency of the production process.
[0046] Step C: The feeder 1 moves to the starting position of the kiln feeding area 106, and the feeding system 6 is started to convey the batch material, and finally the feeding belt 4 conveys the batch material to the discharge end of the feeding arm 3; the feeding arm 3 begins to extend and retract, and the material is fed; Start the feeder 1 and move it to the starting position of the kiln feeding area 106 through the feeder transverse transmission device 8. Start the feeding system 6, and the screw conveyor 62 starts to work, conveying the batch material from the batch material bin 61 to the guide trough 63, and finally dropping it onto the belt of the feeding arm 3; the belt starts to rotate under the drive of the first servo motor 53, conveying the batch material to the discharge end of the feeding arm 3; the feeding arm 3 starts to extend and retract under the drive of the feeding arm telescopic transmission wheel 72, and preliminarily spreads the batch material on the liquid surface of the kiln.
[0047] Step D: The data monitoring module monitors the distribution of the batch materials in real time. The collected signal data is fed back to the control system for intelligent conversion and then output to the transmission control for supplementary feeding at fixed points or local areas; Step E: When the kiln reaches the predetermined melting amount or melting time, the feeder 1 is stopped and inspected, maintained and serviced to ensure that it can operate normally next time.

Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
